ABSTRACT:
An air cleaning device produces a vertical plane of moving air to block migration of airborne impurities from one area to another, and to create a low pressure area which remotely attracts impure ambient air to it. The device may have one or more restricted air inlets orthogonal to the vertical plane of moving air, with restrictions creating increased air velocity at the inlets resulting in a low pressure zone which attracts impure ambient air to the inlets. A single stage activated charcoal filter which removes chemicals and odors may be provided within the device, as well as an ionizer which electrostatically removes particulates.
